No, no. What we can do is use an existing tax—for example, part of the GST or business income tax—and then allocate it to the provinces. The thing that's important here, of course, goes back to the idea I'd put forward with Trevor Tombe.
I think the URL of our paper is embedded in the text I sent to the clerk. It's available to you and is already online.
The idea here is that the provinces will actually have to be consulted over any change to the tax rate. Really, it would become a shared tax so that the federal government could not suddenly lower the tax if it's to go to the provinces.
Here again, we actually borrow the government's mechanism of the Canada pension plan, where you need two-thirds of the provinces representing two-thirds of the population to actually support a change in order for the change to occur. I think that's a way to protect the provinces. If it's really a tax-sharing system, and the tax is being shared, the provinces should have a word to say in terms of increasing or decreasing the tax rate.
This is the idea we put forward in our paper for the University of Calgary policy school. There is another version of the paper. As soon as it's published in an academic journal, I will circulate it to this wonderful committee.
